Milling Cutters

New Beyond KYS40-grade solid ceramic endmills from Kennameta are presenting orders-of-magnitude improvements in machining high-strength nickel-based alloys, roughing at cutting speeds up to 3,300 SFM (1000 m/min) with tool life two to three times longer than comparable solid-carbide tools.

Experienced manufacturers know that when milling, three main considerations predominate: metal removal rate, tool life, and surface finish. All three are critical to successful metalworking, but often one will predominate. Manufacturers facing parts requiring 90-degree shoulders also know that achieving true 90-degree shoulders and minimizing the scallop or step marks between passes absolutely requires a high-performance cutter. The new Mill 4-15 platform from Kennametal is that best-in-class system, according to the company.

With eight cutting edges, the new KSSM8+ face milling platform from Kennametal is focused on maximum metal-cutting performance in cast irons and steel workpieces at a low cost.

Iscar Metals Inc. has expanded its popular HELIDO milling cutter family to optimize facemilling, especially for cast iron. The new HELIDO S865 FSN mill has a 65^o lead angle to minimize burr formation and edge breakout, which can complicate cast iron applications.

A major expansion of the ISCAR HELIDO 845-13 mill family brings the efficiency and economy of these popular tools to a wider size and application range.

ISCAR has expanded its popular line of HELIDO ROUND H400 fine-pitch mills to improve profile machining and ramping over a wider range of applications.

A new high-feed milling cutter extends the benefits of ISCAR's HELITANG UPFEED tangential milling cutters to ramping work as well.

Iscar Metals' HELIDO S890 FSN is a new family of right-hand indexable face mills with an 88°Cutting edge angle (2 degree lead) with 8 helical cutting edges, which can be used for up to 9mm depth of cut.

ISCAR introduces the ISCAR HELIQMILL 390 line, a new step of development of the insert with helical cutting edge.

The chatter or vibration in metal cutting poses an eternal challenge for manufacturers. The ISCAR products of the latest HIGH QLINE family of cutting tools offer an interesting solution: Indexable Milling Insert with an asymmetric shape.
